Atlas scientific EZO circuits

[Le-bo2d9]

Hi,

Atlas scientific have circuits that measure water levels PH, ORP, DO, EC and RDT(temp) all communication is serial or I2C.
Is it poiible to use the circuits on the ESP8266?

Kind regards Koen

I looked at a couple and they are I2C and 3.3 - 5v compatible. I think it is possible. I did not find any arduino libraries, but they could be there somewhere. It appears they have different default I2C addresses so I don't see any reason it couldn't work, given enough effort to develop the plugins.

Hi Drum,

THX for the reply.
On the web site of Atlas scientific there are sample codes available in de download section of each circuit

I will order an esp8266 and a probe circuit. But this will be in the far future.

Kind regards

Koen

I was looking into these. I ended up just grabbing a DFRobot PH sensor with industrial probe for continuous readings/logging. I had it working pretty good(readings on par with my bluelab) with an arduino and LCD.. Now im scratching my head trying to figure out how I am going to do this with the ESP. The DFRobot sensor has analog output.
Any links on someone with a similar problem? serial? I just uploaded R140 and noticed there is a serial option. Anyone have some details to make this a little less time consuming? lol.. I have two ESPs logging 5 temp and humidity sensors right now into Node-red. So im not a total Noob.
Thanks!

As I'll need a Dissolved Oxygen probe, I think I'll end up with the pricey Atlas

Hello, were any of you able to read DO with ESP?
